Royal Air Force Langham or more simply RAF Langham is a former Royal Air Force station and was originally laid out with three grass runways.
The station became fully self-supporting in 1942, when it was upgraded with three concrete runways (tar-covered), three T2 type and four Blister hangars, an encircling perimeter track and 36 spectacle-shape hardstandings, plus a Type 12779/41 control tower and normal Mk 2 approach lighting for night operations.
Primarily used by RAF Coastal Command throughout the war, it was placed on Care and Maintenance in 1947, but reactivated during the Korean War. It was later used as an emergency landing strip for RAF Sculthorpe, before final closure in 1961.

The station was purchased by Bernard Matthews Ltd, who constructed turkey sheds on the runways. This has preserved large sections of the runways.
A small aircraft repair and maintenance facility is based in buildings to the south side of the airfield, and uses the southern perimeter track and adjacent grass area for flying operations.
Surviving buildings on the site include the control tower and a dome trainer building used for the instruction of ground-to-air anti-aircraft gunnery. Langham Dome, which sits on the edge of the former base, is one of only six remaining training domes in the United Kingdom and was built in 1942. Film of enemy planes was projected onto its walls for target practice. The structure has been restored and a museum installed following grants from English Heritage and the Heritage Lottery Fund.

You are looking for a magnetic container cache hidden close to the N/S where the road bisects it.
While searching make sure to take a few minutes to appreciate the location and imagine what it must have been like in times past- certainly a big difference from the peace that it currently enjoys disturbed only by the odd passing car, hares, red kite circling overheard and skeins of geese heading inland to rest.
Be aware of traffic to and from the sheds that are accessed through the nearby gates.
